State different type of mortality rate

Mortality rate is the calculation of the number of deaths per a specific sub category. Scientists study many different types of mortality rates, such as crude mortality, infant mortality, or maternal mortality. The cause-specific mortality rate is the mortality rate from a specified cause for a population. The numerator is the number of deaths attributed to a specific cause. The denominator remains the size of the population at the midpoint of the time period. The fraction is usually expressed per 100,000 population. Mortality rate (or death rate) is usually expressed in units of deaths per 1,000 per year or it could be described as percent dead in a specific period of time. For example in the US: Lung cancer has a high mortality rate (46.0 per 100,000) vs thyroid cancer (0.5 per 100,000) which has a low mortality rate.
